Thanks to the tang police for showing up again. Yes i know the achilles will need a bigger tank. As it stands it is a very juvenille tang and it is doing very well in the current tank it is in. I am glad that there are so many people concerned with the conservation and well being of marine life like I am. All that i really was curious about was if there was any other tang or tang like fish that would be in any way compatible with the achilles. Yes I have read the primer. Yes I have looked into the fish and talked with my LFS. These forums are to share knowledge and experiences of the other people posting here. Thank you to the people who actually had some input that pertained to the topic of the forum it is greatly appreciated. A little bit of help will go quite a long way to building a solid knowledge base. Before trying to condem another person who shares the same passion that you do look into the situation and get some facts.
